Section 4
Troubleshooting the HTT-1
The HTT-1 does not require calibration. If the HTT-1 does not operate as described in the
Theory of Operation section, and the equipment connected to the HTT-1 has been verified to be
in good working condition, then the HTT-1 should be returned to Compliance West USA for
inspection and/or repair.
Table 3 shows expected results for a known good hipot tester for all recommended operating
modes.
